Here’s everything you need to know about Sky Original documentary Murder at the Post Office, starring Diana Garbutt and Robin Garbutt through archive footage:

Murder at the Post Office Synopsis

Murder at the Post Office is a 2025 documentary series that examines the murder of Yorkshire postmistress Diana Garbutt and the controversial conviction of her husband amid growing doubts linked to the Post Office Horizon scandal.

In 2010, the quiet village of Melsonby was shaken when Diana Garbutt was found dead inside the post office she ran with her husband, Robin. Investigators quickly focused on Robin, and prosecutors argued that financial strain, a missing sum of money, and marital tensions led to a fatal confrontation. Despite his insistence that an intruder was responsible, Robin Garbutt was convicted in 2011 and sentenced to life in prison.

More than a decade later, the documentary revisits the case through a new lens. With the Horizon computer system now widely discredited for its role in wrongful prosecutions, the series questions whether evidence used at trial was fundamentally flawed. Through interviews, archive footage, and a careful re-examination of the investigation, the documentary explores unresolved doubts and the possibility that one of Britain’s most troubling convictions could be reopened.
